The last part doesn't seem right and this gives us the following
possible values gpio0-9, gpio10-99, gpio100-106 and gpio110-116.

I think the correct pattern would be:
	"^gpio([0-9]|[1-9][0-9]|10[0-9])$"

Please include a space between the unit address and '{'.

This line is indented with tabs, the rest with spaces.

With those changes this looks really good.

Thanks,
